It is possible that sex-changing fishes alter otolith composition, and thus sensory-range specificity, to optimize life history in accordance with their new reproductive mode. 展开 关键词: reef fish, sex change, otolith, hermaphroditism, life-history transition ...
Sex-changing fish Trimma okinawae can change its sex back and forth from male to female and then to male serially, depending on the social status in the harem. T. okinawae is well equipped to respond to its social status by possessing both ovarian and testicular tissues even though only on...
只有体型最大的雌鱼才会经历这种转变。But the change enables them to have more mates, so they will have many more offspring carrying their genes.这种转变让其能够拥有更多的配偶，因而携带其基因的后代也会更多。But a new male can't afford to be complacent.但新的统治者不可掉以轻心。Inside the bo...
Climate change overruns resilience conferred by temperature-dependent sex determination in sea turtles and threatens their survival Temperature-dependent sex determination (TSD) is the predominant form of environmental sex determination (ESD) in reptiles, but the adaptive significance o...

Simultaneous loss of multiple males from large, multi-male social groups of the coral reef fish, Anthias squamipinnis, induces an equivalent number of females to change sex. One-to-one replacement could be produced in large groups if the group was organized according to either of two hypotheses...
It is an axiom of vertebrate behavioural endocrinology that full expression of a male behavioural phenotype depends on testicular influences during development, in adulthood, or both. Sex change in fishes challenges this necessity: behavioural changes are often rapid and greatly precede gonadal changes....
When ten to twenty females and one or two males were kept together for several months there was no change in morphology or behaviour to indicate sex change, although cut sections of these fishes revealed advanced degeneration of the ovaries. 展开 ...
Diversity and flexibility of sex-change strategies in animals Here, we review recent empirical advances that have improved our understanding of why and when sex change occurs. We show that sex-changing animals use a g... PL Munday,PM Buston,RR Warner - 《Trends in Ecology & Evolution》 被...
Dive rates did not change with age or differ among pods or between males and females, although analyses restricted to adults showed that adult males dove deep significantly more frequently than adult females during the day. For all whales, dive rates and swim speeds were greater during the day...
